Llywelyn

Llywelyn is a Welsh masculine given name of historical significance. It is derived from the elements "llw" (oath, pledge) and "elyn" (image, likeness), and can be interpreted as "leader" or "like a leader," or "oath-keeper." It is strongly associated with figures of Welsh royalty and leadership, particularly those who sought to establish and maintain Welsh independence.

The name achieved prominence primarily through two significant Welsh rulers:

• Llywelyn the Great (Llywelyn ap Iorwerth, c. 1173 – 1240): Prince of Gwynedd and ruler of all Wales de facto for much of his reign. He is considered one of the most important and influential rulers in Welsh history, solidifying power and establishing laws.

• Llywelyn the Last (Llywelyn ap Gruffudd, c. 1223 – 1282): Prince of Wales recognized by the English Crown under the Treaty of Montgomery in 1267. His death in 1282 marked a significant turning point in Welsh history, leading to the conquest of Wales by Edward I of England.

Beyond these prominent figures, the name has been used by other individuals in Welsh history and continues to be used as a given name in Wales and among people of Welsh descent today. It carries a strong sense of Welsh heritage and national identity. The spelling variations are rare, typically remaining close to the standard "Llywelyn."
